Troika provides expert consultancy services to support specific seismic data management projects. Combinations of software modules – optionally including customised add-ons and tailored automated workflows – can be assembled, installed in the user’s facilities, and supported as required. Leveraging decades of specialised industry experience, customised modular in-house or hosted training courses can be provided addressing topics such as legacy and modern seismic tape media and formats and the efficient use of data management software.
Troika has built a range of capabilities for independent 3rd party quality control of legacy data transcription and life-of-field seismic (LoFS) 4D acquisition. QC of transcription projects is typically based on checking a representative sample of input and output tapes, database accuracy and reliability, and expert analysis of the transcription procedures. For LoFS acquisition projects, Troika provides independent 3rd party services to remotely measure repeatability between surveys through a responsive interface to QC attributes. Versatile automated software workflows running 24/7 via remote transfer of data to and from vessels or rigs enable in-time response to E&P companies in the event of discrepancies between planned and actual survey parameters. This service can be particularly valuable when operators use different acquisition suppliers from one 4D survey to the next.

Troika International provides software and specialist services for transcription and pro-active Data Management procedures and processes.
The Troika team have worked in transcription and Data Management for many years and have developed training courses to hand this knowledge over.
Within the industry, knowledge is often lost due to retirement and career progress. Troika’s training will assist in providing expert knowledge in the field of seismic data formats and media.
Troika’s tailored training courses can be provided either in group sessions or on a one-to-one basis. The training can be held at our training facilities in Tunbridge Wells or Houston, at your preferred location or remotely via virtual services. The courses can be offered in bitesize chunks or in-depth sessions, working around your schedule and specific requirements.

Leveraging decades of specialised industry experience, courses can be provided addressing topics such as legacy and modern seismic tape media and formats. Modules will also cover the readability of tapes and how to recover data to ensure that any transcription work carried out maximises the recovery of legacy information. Troika also provide courses for data transcription QC and verification of datasets for processing and loading to workstations.
Troika provides support from industry professionals experienced in seismic issues ranging from acquisition, data loading, processing, and uploading to workstations for analysis and interpretation. Troika’s experts will take a pragmatic approach to address your particular seismic data management challenges and will make practical recommendations to ensure the long-term sustainability of your valuable data assets.
QC and Validation
Troika software provides efficient tools to ensure that seismic datasets are contract-compliant and adhere to the guidelines set by the SEG Technical Standards Committee. It can also help in adapting processing workflows to provide exploration and production (E&P) operators and other users with more fully and accurately populated datasets. Troika also has the expertise and knowledge to provide advice and support to companies embarking on tape transcription projects by helping in the formulation of tenders, evaluating bids, and offering third party QC on the resulting data and processes. This service helps data owners to have increased confidence that their data transition has been managed correctly and securely.
For LoF acquisition projects, Troika provides solutions to remotely measure repeatability between surveys through a responsive interface to QC attributes. Versatile automated software workflows running 24/7 via remote transfer of data to and from vessels or rigs enable in-time response to E&P companies in the event of discrepancies between planned and actual survey parameters. This service can be particularly valuable when operators use different acquisition suppliers from one 4D survey to the next.
The scope of work
- To provide near real time QC as the data is acquired
- A 350MB SEG-D shot record is delivered to the Troika disk every 11 seconds
Troika provided a web browser-based dashboard showing the planned, live & historic information:
- Shot header information
- First break images
- Near offset amplitude images
- Pre-planned vs live vessel location
- Source statistics (gun pressure)
- Aerial and 3D RMS plots
Once the line was completed the shots were then archived to tape in sequence
